Makes approximately 2 dozen cookies
*I don't recommend half or double batches. Instead, make a whole batch, bake what you want, portion and freeze the rest.
Another note: Keep in mind this is a "chocolate chip" cookie and therefore the quality of the final product will be greatly effected by the quality of the chips used. Although the semi-sweet "morsels" that we all know from the yellow bag are serviceable, I'd suggest combining such kid-friendly fodder with something a bit more daring, say dark chocolate chips/chunks in the 68% cocoa range. Oh, and remember you can chop your own.
